Not everyone was on board when Prince Harry started dating Meghan Markle — including Harry’s brother, Prince William. In a new U.K. documentary called William & Harry: Princes at War, royal experts revealed that William and his wife, Kate Middleton, were concerned about Harry’s new relationship.

“The biggest cause of their so-called rift was Wills tried to warn Harry when he met Meghan not to rush into it,” Sky News broadcaster and journalist Carole Malone said in the documentary, which aired on Channel 5 on Sunday, August 18. “He’d only known her for less than a year when they got engaged. He sat him down and just told him to take it a bit slow, not to run at it.”

However, the 34-year-old redhead didn’t seem to listen to his older brother’s advice. He proposed to the 38-year-old American — who was previously married to Trevor Engelson — in November 2017, and they tied the knot in May 2018.

“It was all so quick that William and Kate didn’t have a moment to get to know Meghan because Harry hardly knew Meghan,” Ingrid Seward, royal expert and editor in chief of Majesty magazine, said about the royals meeting Meghan for the first time. “And, of course, quite naturally William and Kate would have thought, ‘Oh, she’s been married before, she’s older than Harry, I hope she’s going to make him happy.’ Anyone would think that.”

After William, 37, and Kate, 37, revealed their true feelings to Harry, he lost his temper with his older brother and sister-in-law. Harry “went ballistic and said, ‘You’re trying to wreck this relationship before it’s even started,’” The Sun’s royal correspondent Emily Andrews revealed in the film.

Ultimately, Harry didn’t think it was fair that William wasn’t giving Meghan a shot. “Harry supported William from the outset of his relationship with Kate, and he felt very let down that he wasn’t getting his brother’s full 100 percent support with the relationship with Meghan,” author Katie Nicholl said.

After Harry welcomed his son, Archie, in May, and Prince William became busy with his three kids — George, 6, Charlotte, 4 and Louis, 16 months — the brothers are no longer as close, a source told In Touch exclusively in July. “The Queen hoped that the arrival of Archie would bring her grandsons together,” the insider dished. “Whilst they still talk, their relationship isn’t back to how it used to be.”

The source continued, “The boys are both married and have families of their own, so it’s only natural that they’ve drifted apart. There are still unresolved problems with Meghan — although William has accepted her into the family, her strong opinions have rubbed him and some of the other royals up the wrong way.”

Hopefully, these two can make up sooner than later!
